The unlawful sexual association of men and women. Although adultery generally refers to sexual intercourse between a married person and someone other than his or her spouse, in the scriptures it may also refer to the unmarried.

    Sometimes adultery is used as a symbol for the apostasy of a nation or a whole people from the ways of the Lord (Num. 25:1–3; Ezek. 16:15–59; Jer. 3:6–10; Hosea 4).
